🔧 Starter Motor - Replacement

The starter on your Stinger sits low on the engine/transmission area and usually requires battery disconnect and under-vehicle access to remove safely. This job is doable at home, but space is tight and the electrical connections must be handled carefully.

Difficulty Level: Advanced | Estimated Time: 3-5 hours


⚠️ Safety & Precautions

  • Disconnect the negative battery terminal first. The starter has direct battery power.
  • Wait at least 5 minutes after disconnecting the battery before working around electrical connectors.
  • Use jack stands on solid ground. Never rely on a floor jack alone.
  • Keep hands clear of the exhaust and transmission case. These parts can stay hot for a long time.
  • Do not short the starter power cable to ground.

🔧 Required Tools

You'll need the following tools for this repair:

  • 10mm socket
  • 12mm socket
  • 14mm socket
  • Ratchet
  • Short extension
  • Long extension
  • Torque wrench
  • Flat-head screwdriver
  • Trim clip tool
  • Floor jack (rated 3-ton minimum)
  • Jack stands (rated 3-ton minimum)
  • Wheel chocks
  • Safety glasses
  • Mechanic gloves

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Starter motor - Qty: 1
  • Starter mounting bolts - Qty: 2
  • Starter electrical nut - Qty: 1

📋 Before You Begin

  • Park on level ground and set the parking brake.
  • Put wheel chocks behind the rear wheels.
  • Disconnect the negative battery cable before touching starter wiring.
  • Raise the front of the vehicle and support it with jack stands.
  • Take a photo of the wire routing first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect battery power

  • Use a 10mm socket to loosen and remove the negative battery terminal.
  • Move the cable aside so it cannot spring back and touch the post.
  • Wait at least 5 minutes before continuing.

Step 2: Raise and secure the vehicle

  • Use a floor jack (rated 3-ton minimum) to lift the front of the vehicle.
  • Support it with jack stands (rated 3-ton minimum).
  • Make sure the vehicle is stable before going underneath.

Step 3: Remove lower engine cover

  • Use a 10mm socket or trim clip tool to remove the undertray fasteners.
  • Lower the cover and set it aside.
  • This opens access to the starter area near the transmission bellhousing.

Step 4: Locate the starter

  • Find the starter mounted where the engine meets the transmission.
  • Identify the large battery cable and the smaller control wire.
  • Label the wires if needed.

Step 5: Disconnect the starter wiring

  • Use a 12mm socket to remove the nut from the main power cable terminal.
  • Remove the smaller connector by pressing its lock tab with a flat-head screwdriver if needed.
  • Move both wires out of the way.

Step 6: Remove the starter mounting bolts

  • Use a 14mm socket, ratchet, and long extension to remove the starter bolts.
  • Support the starter with one hand as the last bolt comes out.
  • Carefully lower the starter from the vehicle.

Step 7: Install the new starter

  • Position the new starter in place by hand.
  • Start both mounting bolts by hand first to avoid cross-threading.
  • Use a 14mm socket to tighten the bolts.
  • Torque to 44 Nm (32 ft-lbs).

Step 8: Reconnect starter wiring

  • Reconnect the small control wire until it clicks or seats fully.
  • Install the main power cable with a 12mm socket.
  • Torque to 9 Nm (80 in-lbs).
  • Make sure the cable cannot touch nearby metal parts.

Step 9: Reinstall the lower cover

  • Lift the undertray back into position.
  • Use the 10mm socket and trim clip tool to reinstall all fasteners.
  • Make sure all clips are fully seated.

Step 10: Reconnect battery and test

  • Reinstall the negative battery terminal using a 10mm socket.
  • Start the engine and listen for a normal crank.
  • Check for warning lights and verify the engine starts every time.

✅ After Repair

  • Start the engine several times to confirm consistent operation.
  • Check that the starter cable and connector are secure.
  • Inspect underneath for any loose panels or tools left behind.
  • If the engine cranks but does not start, recheck the battery connection and starter wiring.
